A novel algorithm that combines genetic, environmental, and clinical data could be useful for predicting whether people with a first onset of multiple sclerosis (MS)-like disease — known as clinically isolated syndrome (CIS) — will experience relapses or a worsening of their disease over time. The…

Adverse childhood experiences (ACEs) did not increase the risk of multiple sclerosis (MS) development and were not associated with worse clinical outcomes, a recent study reported. These findings add to the complexity of the potential relationship between ACEs and MS that has emerged across several research studies. “Our primary…

You may have heard about the research that’s just been published about the Epstein-Barr virus (EBV) and multiple sclerosis (MS). The Harvard T.H. Chan School of Public Health study reports that being infected by EBV raises the risk of developing MS by 32 times. This isn’t a small or…

Epstein-Barr Virus May be Leading Cause of MS, Raising Risk by 32 Times Several studies over the past few years have suggested a link between the Epstein-Barr virus (EBV) and multiple sclerosis (MS), but this one is huge, both in the number of participants and in the length…

Among people with multiple sclerosis (MS), a progressive disease type and the use of anti-CD20 therapies — such as ocrelizumab and rituximab — were associated with an increased risk of death from COVID-19, a new meta-analysis revealed. “We hope that these findings … may help neurologists in optimizing…

People with multiple sclerosis (MS) are at greater risk of developing cancer than the general population, according to a French study involving nearly 100,000 patients. This increased risk was particularly apparent for prostate, breast, colorectal, and anal cancers, as well as cancers of the trachea, bronchus, and lung. The researchers…

Cognitive dysfunction in patients with multiple sclerosis (MS) is predictive of worse outcomes, including clinical progression of the disease and a higher risk of mortality, according to a new study. “This review revealed that cognitive dysfunction … was associated with higher odds of transitioning from [a] relapsing–remitting course to…

People with a higher genetic risk for multiple sclerosis (MS) are significantly more likely to develop the disease at an earlier age, a large study found. Specifically, those with the highest genetic risk were on average five years younger at the time their symptoms started than those with the…

Children and young adults who spend more time outdoors in the sunshine are less likely to develop multiple sclerosis (MS), according to a new study, which suggests that sunshine might help to protect against the disease. “Advising regular time in the sun of at least 30 minutes daily especially…

The use of oral contraceptives does not increase the risk of a second attack of symptoms or the progression of disability in women with clinically isolated syndrome (CIS) or early stage multiple sclerosis, a study demonstrated. Notably, the researchers also “did not find a protective effect on disability…

The Multiple Sclerosis Society of Canada (MSSC) has partnered with the National Multiple Sclerosis Society (NMSS) to support a Canadian-led study investigating the earliest predictors of multiple sclerosis (MS) during the so-called prodromal period across diverse groups. A prodrome is a set of signs or symptoms that…

Among people with nervous system damage indicative of multiple sclerosis (MS), but who don’t yet have the disease — a condition known as radiologically isolated syndrome or RIS — the risk of progressing to full-fledged MS is higher for those who are younger, have spinal cord lesions, and have…

Not drinking alcohol significantly increases the risk of developing multiple sclerosis (MS), especially if a person also is a current or former smoker, according to a new study. These findings add to the knowledge, discovered in multiple previous studies, that alcohol decreases the activity of the immune system. According…

People who contract infectious mononucleosis — colloquially known as “mono” — during childhood or adolescence are at a roughly two to three times greater risk of developing multiple sclerosis (MS) as adults, a large population-based study suggests. Notably, the study points to mono itself — independent of other factors…

Australia’s National Health and Medical Research Council (NHMRC) is giving a total of AU$6.75 million (about $5 million) in grants to advance research into multiple sclerosis (MS), including risk factors for the disease, preventing falls, and harnessing viral-immune system interactions to improve patients’ lives. The three investigator grants,…

One year of Ocrevus (ocrelizumab) treatment does not increase the risk for a rare brain infection — called progressive multifocal leukoencephalopathy (PML) — in people with multiple sclerosis (MS), a study suggests. The study, “Risk Assessment of Progressive Multifocal Leukoencephalopathy in Multiple Sclerosis Patients during…

Mutations in the John Cunningham virus may serve as an early predictor for a rare brain infection in multiple sclerosis patients receiving Tysabri (natalizumab), a study suggests. However, more research is required to investigate the specific mutations in the viral VP1 gene, and validate the risk of the…

People with multiple sclerosis (MS) are not at greater risk for severe COVID-19 outcomes, according to a study of more than 150,000 hospitalized people in Germany. The study, “Multiple sclerosis is not associated with an increased risk for severe COVID-19: a nationwide retrospective cross-sectional study from Germany,” was…

The presence of a light-sensing protein in the brain during the early stages of fetal development may help to explain why certain neurological diseases, like multiple sclerosis (MS), are more common among people born at specific times of the year, a study found. The researchers, who noted that people…

People who develop colon cancer are more likely to die in the first year, from that cancer or other causes, if they also have multiple sclerosis (MS), a new study indicates. MS disability seems to contribute to this association. “These results warrant further investigation to determine what factors may…

Depression in multiple sclerosis (MS) patients greatly raises their risk of vascular disease and death by any cause, a study that compared this patient group with other patients and a matched public reported. Its researchers recommended further work to determine “whether effectively treating depression” might lower these risks for these…

Experiencing serious infections during adolescence is tied to an increased risk of developing multiple sclerosis (MS) later in life, but those occurring in childhood don’t increase MS risk, according to a new Swedish study. The study also found that certain types of infections, especially those that affect the central…

A variation in a gene called STK11, previously shown to increase the risk for multiple sclerosis (MS) among Caucasians, is now also linked to a greater likelihood of MS in Black people. In fact, the variation was significantly more common in Black MS patients with secondary progressive MS (SPMS),…

Exposure to multiple sclerosis (MS) disease-modifying therapies (DMTs), and particularly immunosuppressive DMTs, does not increase the risk of developing a severe form of COVID-19, or of dying from the disease, when adjusting for known risk factors, an Austrian registry-based study found. These findings add to data showing no…

Hypertension — high blood pressure — triples the risk of severe walking disability in Hispanic and Latino people with multiple sclerosis (MS), a new observational study reports. The study, “Hypertension and hypertension severity in Hispanics/Latinx with MS,” was published in the Multiple Sclerosis Journal. Although…

Genetic susceptibility to multiple sclerosis (MS) depends on an individual’s particular combination of multiple risk variants, a study reveals. The study, “Genetic susceptibility to multiple sclerosis: interactions between conserved extended haplotypes of the MHC and other susceptibility regions,” was published in the journal BMC Medical…

Inherited or familial multiple sclerosis (MS) occurs most frequently in children, women, and people living in warmer climates, a new study suggests. Prevalence rates also differ according to geographical areas, with Canada exhibiting the highest rates and Hungary the lowest. The study, “The global prevalence of familial multiple sclerosis:…

Children born to women with multiple sclerosis (MS) are not at a higher risk of brain disorders than are children whose mothers don’t have this disease, an observational study reported. However, children born to women with a family with a history of other autoimmune conditions and brain disorders, or…
